Soil and Fertilizer

Red milkweed prospers in drained soil with a pH level between 6.5 and 7.5. It needs a nutrient-abundant soil to support its development and blooming. Fertilize red milkweed with an even fertilizer, for example a 10-10-10 recipe, toward the beginning of spring before new development shows up. Apply the manure at a rate of 1 pound per 100 square feet of planting territory. Rehash the application like clockwork during the developing season. Keep away from over-manuring, as it can prompt unnecessary foliage development to the detriment of blossoms. Screen the soil quality consistently to guarantee it stays rich and all around depleted for ideal red milkweed development.
